must confess ...

I was always against Samsung. Had before getting to bring my NEN Sony LCD or Panasonic plasma. The multimedia capabilities of this equipment but have made me zuzulegen the B650.
I have this 40-inch TV is not ordered here at Amazon.
Have my 1TB Trekstor FP connected to the side USB ports and so far there was nothing that he has not played: even MKV WMV AVI and. Since only up to 1280x720 pixels I MKV, I can not say whether there funzen higher resolutions. Coils is also possible: easy on the + Control Pad to use button "to the right" or "left". While there is still a normal roundworms button below, but is much too lame. He is said to not only FAT32, but also NTFS disks accept. Has so far only FAT test. Otherwise, you can get on the Samsung side more information you.
It is operated only on an analogue connection, but as I apparently have a pretty good signal, the picture is more than acceptable.
Image settings (contrast, brightness, etc.) can be made independently for each source, ie for AV1, AV2, norm.TV, HDMI1 etc.
The foot is gröstenteils glass.
Clouding there is not, in any case I had not noticed.
The black is very very black - see little difference from the tube.
A power switch does not exist, but the standby power consumption is less than 0.3 Watt / hour.
The channel change is rapid.
Angle to 45 degrees in any direction is good. Moreover, the picture is of course a bit milky. But is all so, except plasma.
Remote responds well and is even illuminated.
Annoying: After the tuning was done, the sort the services began. And that's really tedious, because you constantly need new for each transmitter to the menu. Incomprehensible, but you do it actually only once and then never again.
Had me the B750 Samsung looked at - but seems out of 200 Hz and a different design no longer be able to / have.

Still very happy with the TV.
Yet, two additional information: Yes, NTFS disks are detected clearly from 650s. And MKVs Full HD also work well, only DTS audio tracks he can not play. Had been a few WMVs that he could not see.
A little tip for all PS3 Slim owners whose PS3 connected via HDMI: In the system settings of the PS3 there is a point "HDMI Control". If the item is enabled, the following happens:
When the TV is off and the PS3 is turned on, the TV is automatically turned on with.
When the TV is on and the PS3 is turned on, turn the TV from norm. Analog TV program on the HDMI the PS3.
If both devices are on and the TV is turned off, the PS3 comes out with.
For these functions, the Samsung is "Anynet" responsible and ONLY works with the PS3 Slim and not with the old.
